This paper reports on the results of the exploratory containment iodine chemistry calculations related to the first Phebus-FP test. The code benchmark results show that mechanistic codes (INSPECT and LIRIC) are in agreement for molecular iodine concentration in the gaseous phase, whereas empirical codes (IODE and IMPAIR) are in disagreement because they model differently HOI disproportionation and use different radiolytic constant values. The aim of the benchmark exercise is to help to explain the reasons for codes' inconsistencies and to improve understanding of the code results for Phebus-FP tests.
